摘要(Abstract)：

复合材料往往由导体-绝缘体组成,当导电相含量超过临界体积分数,即逾渗阈值时,复合材料有可能出现负介电常数。由于金属陶瓷有其难以避免的局限性,同样能够展现出负介电性能的高分子/碳复合材料便应运而生。该类复合材料在传感器、隐身衣、可穿戴电子设备等方面的应用前景非常广阔。主要介绍了高分子/碳复合负介电材料的分类、性能以及应用研究。
Composite materials are often composed of conductor-insulator. When the conductive phasecontent exceeds the critical volume fraction, that is, the percolation threshold, the composite material mayhave a negative dielectric constant. Due to the unavoidable limitations of cermets, polymer/carbon compositematerials that can also exhibit negative dielectric properties have emerged. The application prospects ofsuch composite materials in sensors, stealth clothing, wearable electronic devices, etc. are very broad. Theclassification, performance and application research of polymer/carbon composite negative dielectricmaterials are mainly introduced.
